The present paper aimed at seeking a teaching method of nudge design which is blended with fine art for the prevention of safety accident which is one of the cross curriculum. Because of the trivial carelessness and the lack of awareness for safety, big and small safety accidents have been occurred all over the areas in the society, although our lives have got more convenient and bountiful day by day. Therefore, the writer made the classes of Experience Areas and Expression Areas in the department of Fine Art connected and designed them in order to help the students to be aware of the usefulness of nudge design that can prevent safety accidents. Especially, the problems were drawn out via their discussion on the prevention of safety accident and nudge design was set up to improve the problems and apply them to the real life. Nudge design has the merit of solving social problems or problems that happen in the daily life via visual communication. Accordingly, it is thought that fine art education alone can prevent the safety accidents if the students could seek the problems of their daily environments and do a nudge design that could resolve them.
